The object of my invention is to'provide an ac celerator foot pedal adapted to be mounted adjacent the push rod of an accelerator of an automobile, the parts being or" simple, durable andcomparatively inexpensive construction.

More particularly, it is my object to provide an accelerator foot pedal adapted to have a hinged connection with a T-shaped support or .b'olt, whereby one end of the foot pedal resting upon the push rod have loose connection therewith, as well as a slidable connection; so that when the foot of the driver of the automobile is inclined or pressed down, the foot pedal willpush the control or push rod of the accelerator, and

when the weight of the foot is removed from the foot pedal, then and thereafter the spring normally employed in accelerator devices will return the push rod to normal position.

till a further object is to provide a threaded T-shaped bolt for supporting one end of the foot pedal, the leg of the bolt being threaded, whereby it may be adjustably mounted on the footboards of the automobile for securing vertical adjust ment, and the arms of the bolt provide one part of means for forming a hinge connection between the foot pedal and the bolt proper, the foot pedal being capable of limited pivotal movement.

With these and other objects in View, my invention consists in the construction, arrangement and combination of the various parts of my accelerator foot pedal, wherebythe objects contemplated are attained, as. hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawing, in which:

Figure 1 is a top plan view of a portion of the control pedals of an automobile.

Figure 2 is a central, sectional view taken on the line 22 of Figure 1, showing my accelerator foot pedal in section.

Figure 3 is a detail, sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a detail, sectional view taken on the line 4-i of Figure 3, illustrating the hinge connection between the foot pedal element and the bolt or support.

Figure 5 is a side view of a slightly modified form of an accelerator foot pedal, parts being.

shown in section to better illustrate the construction; and

Figure 6 is an end view of the its support.

Inthe accompanying drawing, 1 have used the reference numeral 10 to indicate generally the footboards of an automobile. A push rod 12 is normally provided for controlling the operafoot pedal and tion of the accelerator of-the automobile engine.

' The push rod 12 is provided with a head-like element 14. I

in some cases, a metal plate 16 having a central opening ispositioned upon the floor boards 10 in alignment with an opening 18. 1 The push rod 12 extends through the opening 18 and through the metal plate 16. The plate 16 serves as a guide and has a finished surface for the push rod 12 to operate in and through.

It will be understood that the push rod 12 is normally in a raised position relative to the footboards 10 through the medium of springs nor mally provided for such purpose inconnection withaccelerator devices.

Myaccelerator foot pedalincludes a pedal elemerit A' and a support therefor B. The pedal element A is provided with a metal base plate 20 and a rubber cushion 22. The particular construction of the foot pedal element A is best disclosed in my Letters Patent No. 1,595,710, issued August 10, 1926.

The under surface of the metal base 20 of the foot pedal A rests upon the head 14 of the push rod 12', as clearly shown in Figure 2 of the drawing.

A metal plate 24 provided with a central screwthreaded opening 26 is positioned upon the floor boards 10 adjacent the push rod 12.

A foot rest or button is sometimes mounted within the plate 24.

With my device, the foot button or rest is removed and the bolt or support structure B is positioned within the plate 24. The support B is substantially T-shaped and includes a leg 28 having its lower end screw-threaded as at 30. A nut 32 is positioned upon the screw-threaded portion 30 above the plate 24.

The support B includes'a pair of outwardly extending arms 34, which are slightly inclined relative to horizontal as clearly shown in Figure 3 of the drawing. The purpose of providing the inclined arms 34 is to so arrange'the entire device when in assembled position to provide for comfort of the operators foot when resting upon the foot pedal A.

The support B is threaded into the screwthreaded opening 26 of the plate 24 and after the vertical position thereof has been properly adjusted, then and thereafter the lock nut 32 is moved downwardly until it engages the upper edge of the plate 24.

The support B is then properly positioned and held in such position.

One end of the metal base 20- of the foot pedal A is provided with a pair of rolled portions 36, which provide eyes for receiving the two arms 34. The material between the eyes 36 as at 38 is notched so that when the foot pedal is swung upon its support, the amount of swinging or pivotal movement is limited by the portion 38 engaging the leg 28 of the support B.

It will be noted that one end of the'foot pedal A is thus hingedly connected to the upper end of the support B. a i

The free end of the foot pedal A rests upon the push rod of the accelerator as clearly shown in shaped support 13. The .;T-shaped support B includes a threaded portion and extends through an opening 42 formed in the floor portion 10. A nut and washer l i are positioned above and below theifloor board 10 so that the vertical position of the support B, as shown in Figure 5 may be adjusted as desired.

' The form of device shown in Figure 2is substantially the same as that shown in Figure 5, except, in one case themetal plate of the foot pedal element is lengthened as at and the support B is connected to 'the floor boards through an independent opening without regard to any plate or the like which may be already I positioned upon the automobile floor boards.

The device of'Figure 2 is primarily adapted for use where there is a metal plate similar to that referred to by the reference numeral 24, already provided on the floor boards, whereas in Figure 5, a hole 42 must be drilled in the floor boards, and thereafter the device mounted in position by use of a pair of nuts 44.

It will be noted that my accelerator foot pedal providesa comfortable foot rest and at the same time a control for operation of the push rod 12.

The vertical position may be varied by mere adjustment of the support B.

Within certain limits the position of the pedal itself.may be adjusted, because the support B may be rotated within its plate 24 or within the opening 42 as the case may be.

Some changes may be made in the arrangement and construction of the parts of my accelerator foot pedal, without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:

An accelerator foot pedal comprising a support of T-shape, a threaded mounting plate therefor, and a pedal element hingedly connected with said support and adapted to engage an accelerator push rod, said support having a supporting leg threaded into said mounting plate and supported thereby andsaid pedal element having a pair of cars spaced on opposite sides of said supporting leg and encircling the arms of said T-shaped support to provide such hinge connection. v
